According to a recent report by INGV Naples, the ground deformation of the Campi Flegrei (Phlegraean Fields) near Naples has increased considerably lately.
During the last 12 months, the ground in some places near the town of Pozzuoli was uplifted by about 8 cm.
The largest uplift, recorded by GPS devices, occurred during the months of July-August 2012 and since December. The trend appears to be continuing at the moment.
Such (sometimes dramatic, totaling up to several meters in a few years) ground uplift and subsidence have been known in the Phlegraean Fields since antiquity and are not a new phenomenon. They can usually be explained by normal pressure, temperature and density variations of the giant hydrothermal system of the Campi Flegrei caldera and may not necessarily indicate an imminent eruption.
